Abstract (en)

The present invention relates to a method for manufacturing color filter, a color filter, and a display device including a color filter, to solve the problems of non-uniform edge luminance and color and poor contrast of prior liquid crystal display modules. The method for manufacturing a color filter includes: forming a black matrix on a transparent substrate; forming a photosensitive resist layer on the transparent substrate with the black matrix; disposing a reflection sheet capable of reflecting light on a first side of the transparent substrate to be exposed, the first side being provided with the black matrix; disposing a mask on a second side of the transparent substrate to be exposed, the second side being not provided with the black matrix; and carrying out an exposing process from the second side of the transparent substrate.
